| Abstract: |
| In order to better coordinating the development of grain production system and economic development system, this paper constructs a multiple evaluation index of the two systems and analyzes their correlation mechanism and coupling coordination. By using gray correlation analysis and coupling coordination model, this paper revealed the correlation mechanism and spatial temporal evolution characteristics of China′s provincial coupling coordination between grain production system and economic development system from 2000 to 2016. The results were showed as follows.①There were a high grey correlation between grain production condition & endowment (GPCE) and economic development in China, however grain output efficiency was much closer related with economic development than GPCE. ②From 2000 to 2016, the changing trend of the coupling degree between GPCE, grain production system and economic development system could be divided into the rapid decreasing stage from 2000 to 2004 and the three step changing stage from 2005 to 2016; while to the coupling degree between grain production efficiency and economic development, it showed a continuous decreasing trend during the study period. ③The areas with high and relatively high coupling value between GPCE and economic development were concentrated in central and western regions in China, while the relatively low and low coupling value areas changed from a scattered distribution to a long stripped distribution agglomerating along the coastal areas. ④The agglomeration areas with high and relatively high coupling value between grain production efficiency and economic development gradually shrank and moved westward, while the relatively low and low coupling value areas gradually expanded and agglomerated toward the coastal areas. ⑤The number of provinces with low coupling coordination between grain production system and economic development system decreased from 6 to 3, and changed from an agglomerated distribution in west toward an scattered distribution around the country; The number of provinces with antergic coupling coordination type stabilized at 8 or 9, and changed from scattered distribution toward a long stripped agglomerated distribution along the coastal areas; While the number of provinces with ameliorated coupling coordination type increased from 14 to 18, and showed an agglomerated distribution in central and west, obviously moving to the west. In summary, in order to improve the coordination degree between grain production system and economic development system, China should propel agricultural technology and strengthen the construction of agricultural infrastructure, apply chemical fertilizers and pesticides scientifically and rationally, and implement regional policies based on provincial main contradictions. |
